FILTER.

Specification of Letters Patent.

Application mea rebruary 14, 1919. serial No. 276,936.

To all whom t may concern.' i l Be it known that I, JOHN PHiLrr Pnonsr, a citizen of the United States, residing at Marion, in the county of Marion andState of Ohio, have invented certain new and useful Improvements in Filters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to filters and has for its object to provide certain important improvements infeatures of construction in filters of the type disclosed. in PatentNo. lt, issued to me November 27th. 1911'.

The present invention goes to details of construction and has for its particular object `'to provide a filter of the character slwwn wherein simplicity `and cheapness in con` struction are realized and a filter is produced. which is in all respects admirably adapted to the intended purposes and conditions of use.

Filters of the character here shown` are used to remove objectionable foreign matter from water used in buildings and dwellings, particularly for filtering rain water caught on roofs of buildings and confined in cisterne which usually contain a formation of ini-` purities, commonly known as silt,which renders the water more or less unfit for drinking or cooking ouiposes before it is filtered. In practice it llas been found advantageous to locate the lilter at the exit of the water from the cistern, thus removing the foreign matter therefrom before the water is delivered to the dwelling for use. y

In the accompanying drawings,

Figure 1 is a cross sectional view of my improved filter taken substantially through the vertical center thereof; y

Fig. 2 is a horizontal cross section taken on the line Qf-Q of Fig. 1;

Fig. 3 is a cross section taken on the line 3--3 of Fig. 1; and

Fig. 4 is a cross section taken on the line 4--4 of Fig. 1.

The general construction and arrangement of my present invention, as here shown, is similar to my earlier invention above referred to, but differs from my earlier invention in certain important details which tend to simplify, cheapen `and otherwise improve the device.

As here shown the improved filter consists of a cylindrical-shaped metal casing 1 provided at its open ends at the top and bottom thereof with cover plates 2 which are secured to the casing 1 by means of an annular flange 3 and winged screws l. The flange 3 is pro vided with `projections 5 having threaded apertures therein to receive the screws Ll, the flange being secured to the `casing 1 in any suitable manner, as by brazing or welding.

To form a substantially water-tight joint between the ends of the casing and the cover plates 2, the plates are provided with an annular groove 6 which may be provided with any suitable packing material 7. The flange member 3 is preferably slightly coulitersunk and the ends of the casing 1 are correspondingly flared outwardly, as shown at 8, whereby the flange is held. more securely to the casing and a tight joint is obtained.

Suspended within the casing, adj accnt the Patented Feb. 1, 1921.

upper end thereof from an annular flange 9 is a filter well 10 having its bottom wall webbed as at 11, and having open spaces in itsside walls, as shown in Figs. 1 and 3, and having-an inwardly extending flange 12 at its upper end. Resting upon the flange 12 and suspended within the well 10 from an annular flanged frame or ring 13 is a cylindricabshaped screen 14 which acts to screen the co'arser foreign substances from the water as it passes therethrough. The frame 13 is provided with a strip of metal 15 eX- tending across the cent 'al portion thereof. Disposed above the frame 13 at right angles to the strip 15 `and extending diametrically acrossthe cylinder is a brace 16 having secured therein a wing screw 17 by means of which the ring 13 and the screen suspended thereon is held in fixed relation to the sup porting flange 19. of the well 10. l

The brace 1G is limited in its upward movement by plateslS pivotally secured to the casing'l in any suitable manner which are notched or bifurcated at their lower ends to receive the ends of the bar 16 and to prevent lateral movement thereof. rlfhus it will be seen that the screw 17 willact to hold the screen in fixed relation to the well 1U. VTo remove the screen. the screw 1'2' is retracted until it is free of the cross strip 15; the brace 16 may then be moved laterally and upwardly, or rotatively with the pivoted plates 18 whereby sufficient clearance space is provided between the brace and the screen to admit of the removal of the screen from its supporting frame.

The annular flange 9 is supported in fixed relation to the casing l. by compressing the walls of the casing on opposite sides of` the flange inwardly, as shown in Fig. 1, thus acting to support the flange in fixed relation to the well 10. The flange'may be further secured to the casing by welding or bra/"ing, but for the purposes of the present application of the invention the compression of the casing walls is sufficient to retainA the' flange in osition.

he space in the cylinder between the lower end of the well 10 and the opposite plate 13a, as here shown, may be filled with any suitable filtering material, such as packed Sponges 19 whieh,as has been found, are veryfeflective in removing the oreigx'i substances from the water as it filters therethrough.

It will be observed thatV with the exception of the screen 14 and well 10 the arrangement at both ends of the filter cylinder is the same.

In the present embodiment of the invention it is contemplated to cause the water to enter the Yfilter -at the bottonnand to pass upwardly through filtering material and outat the top. To this end an inlet port 20 andan outlet port 21k are provided. As the water Vmoves upwardly under pressure through the filtering Sponges the silt and other foreign substances are separated from the water, the fine screen gauze of the filter device 14 acting to remove any remaining portions-of foreign substances from the Water after it has passed through the Sponges.

It will be obvious from the described construction that the screen 14 may be located in either endof the casing 1 and that the casing may. then be reversed as to its ends, all the parts affectedby such a change being interchangeable.

As hereshown my construction provides afvery efiicient filter which will Vnot clog. The filter is so constructed that it can be placed On a suction line, discharge line, or water service line, without resistance in pressure also can be used on a gravity flow line or can be attachedv to the spout of a pump or anysouree of water; supply.

When itis desired to clean out the device i or replace the filteringmaterial thefcover plates V2 are removed, the winged screws 17 are'raised and the barsl are turned upon the'pivoted plates18 until they can be lifted upwardly therefrom. The screen and well `what I claim as new and and sponge material may then each be removed without obstruction.

Having thus fully described my invention, desire to ser-ure by Letters Patent, is

1. In a filter, the combination, with a rasing having its wall compressed on opposite Vsides of the center of the casing, of an annular flange supported within thc casing in eachl of said compressions, interchangeable supports cooperating with the resilieetive flanges, and filter material in the casing be tween said supports.

2. In a filter, the combination, with a casing having its wall compressed on opposite sides of the center of the casing, of an annu lar flange supported within the casing in each of said compressions, removable, interchangeable supports coiperalingi with the respective flanges, and filter material in the casing between said supports.

3. In a filter, the combination, with a rasing having its wall compressed on opposite sides of the center of the casing. of an annu lar flange supported within the easing in each of said compressions, interchangeable supports comprising removable braces` arranged transversely in the filter casing and coperating with the respective flanges, and filter material in the casing between said supports.

4. In a filter, the combination` with a casing having its wall compressed on opposite sides of the center of the easing, of an annu lar flange supported within the casing in each of said compressions, removable, interchangeable supports cooperating with the.

respective flanges, a cylindrical filter screen mounted in one of said supports, and filter material in the casing between said supports.

5. In a filter, the combinatiom'with a casinghaving its wall compressed on opposit(` sides of the center of the casing, of an annu lar flange supported within the easing in each of said compressions, removable, interchangeable supports coperatinrf,- with the respective flanges, a cylindrical filter screen mounted in one of said supports and adapted to be interchangeably mounted relative to said flanges, and filter material in the casin@ between said supports.

(In testimony whereof I affix my signature.
